An enormous magnetic filament is perched directly above sunspot 1112 near the sun’s southeastern limb. If the filament collapses (as they often do) and hits the sunspot below, the resulting explosion could be impressive. Actually, it’s already impressive:

Dutch amateur astronomers Jo Dahlmans and Wouter Verhesen took the picture yesterday using a Lunt solar telescope. “We inverted (made negative) the sun’s surface for a stunning display of the snaking filament,” says Dahlmans. “In the distance you can see prominences dancing like flames along the limb of the sun. What a vista!”
